Another one, quite important: BerkeleyDB files are platform dependant, i.e. you cannot use a little-endian file on a big-endian platform and vice versa.

On the other hand, BerkeleyDB doesn't provide network support, it's file based only.

      Well, you might think they can be used, but this notice on the Selecting a byte order shows that they're not actually so usable:

      It is important to note that the Berkeley DB access methods do no data conversion for application specified data. Key/data pairs written on a little-endian format architecture will be returned to the application exactly as they were written when retrieved on a big-endian format architecture.

      Thus, if I'm getting it right, you can actually read a BerkeleyDB file from a different platform, but first you'll have to convert both keys and data to native form in order to use them.
